A step-by-step rotary sprinkler head comprising a sprinkler body having an inlet and at least one outlet communicating with the inlet, a mounting assembly supporting the sprinkler body for rotational movement about a generally vertical axis operable to communicate the inlet of the sprinkler body with a source of water under pressure, a nozzle in the outlet for directing water under pressure communicated with the inlet outwardly of the nozzle in a cylindrical water stream flowing in an upward and outward direction, a drive spoon arm assembly mounted for rotational movement with the sprinkler body and for cyclical movements with respect thereto between a position of stream engagement and a spaced position out of stream engagement for effecting step-by-step rotational movement of the sprinkler body in conjunction with the cyclical movements, and a stream diffusing assembly disposed outwardly of the position of stream engagement of the drive spoon for engaging the cylindrical water stream when the latter is out of stream engagement and diffusing the cylindrical water stream into a fan-shaped spray which is fanned out in a generally horizontal direction, the stream diffusing assembly including upper and lower plates, the lower one of which includes an upwardly and inwardly facing stream engaging surface disposed in a position to engage a lower portion of the cylindrical water stream so that the fan-shaped spray flows in an upwardly and outwardly extending direction after disengagement therefrom.
